8 Claims. (01. 74-535) This invention relates to levers and particuthatwe do not wish to limit the invention to larly to those levers of thetype used for the the particular disclosure illustrated'and thatwecontrols of a motor vehicle or other similar contemplate its usewherever the same may be mechanism. found applicable.

It is desirable in themanufacture of levers Figure 8 is an enlarged transverse sectional ofthis character to grind, or polish the handle view throughthe levertaken substantially on portion .11 while it is unnecessary to nicelyfinish the line 8-8 of Figure '7: the body portion 10 of the lever. Tothis end Figure 9 is a fragmentary view showing one the lower part ofthe handle 11 is provided with end of a modined formof lever similar tothe an embossed or raised portion 27 which acts 7 9 type shown in Figure'I; as a distinct and pleasing separation of the Figure 10 is a sideviewof the parts shown finished handle from the substantially unfln- Iin Figure 9. ished body portion. i We have illustrated several forms oflever of The hollow portion ofthe handle 11 is adapted our invention asof a type used for the control to receive a cup-like member 30,displacement of brakes of a vehicle, but it is to be understood of themember being prevented by flaring the ts and the bottom portion of thecup 30, said washer being fabricated of rubber, felt or other materialpreventing direct engagement of the metal parts so as to prevent chatteror noise which may arise due to vibration of the mechanism with whichthe lever may be used.

.Immediately beneath the manipulating button 20 is a washer 35 ofrubber, felt or other vibration damping material interposed between thebutton and the cup 30 for the purpose of deadening noises arising fromvibration.

In the form of lever shown in Figures 1 and 2, the body portion 10 isformed with an angular portion 22 which connects the two parallelportions of the'lever. The pawl rod 18 is provided with a member or tube19 of non-metallic material as, for example, rubber, fiber, felt and thelike, preventing engagement of the parts.

The means for pivotally supporting the lever will now be described. Thedepending legs 12 of the lever are provided with axially alignedopenings of substantially different diameters for the purpose ofreceiving a bushing 38, the latter being formed with portions adapted tosnugly fit the openings in the legs 12. After the-bushing has beeninserted in the openings in the legs of the lever, the end of thebushing is swedged over as at 37 to hold the parts in fixed relation.The shaft or pivot pin 14 is retained within the bushing 36 by means ofa spring 38 andwasher 39, the latter being held in place by means of apin 40 passing through the extremity of the shaft 14. It will beapparent that through the use of a spring 38, the shaft 14 will bemaintained at all times in one position, the force of the spring servingto prevent noises which might arise due to vibration. The enlarged endof the shaft is suitably supported upon the vehicle by means (notshown).

In the form of lever shown in Figure 4, the cup member 41 enclosing andsupporting a spring 42 is formed at its lower extremity with an inwardlyand upwardly turned flange 43 forming an opening to receive the pawl rod44 similar to the pawl rod 18. The opening in the lower end of the cup41 formed by the flange 43 snugly receives the pawl rod so that there isno lost motion between the rod and the cup to cause noises throughvibration of the parts. The shank 46 of the operating button 47 is alsoformed so as to snugly fit in the upper end of the cup 41 so that nolost motion is present between these parts.

In the form of lever shown in Figure 7 in which the body portion of thelever is in alignment with the handle portion, the pawl rod 50 extendsthrough the hollow portion of the lever and is pivoted to a suitablepawl 52 engageable -with a serrated sector 53 in a manner herein-1,986,227 upper end as at 31. In the form shown in 61 extend rearwardlytoaccommodatea particular form of serrated sector 62 which cooperateswith a pawl 63 pivoted to the extremity of the pawl rod 64. In this formof device the pawl rod is positioned throughout its length between thewalls of the lever, the latter having one of its legs cut away asshownat 65 to accommodate the pivotal connection to the pawl 63. In thisform of device, the pawl rodv is provided with a section of rubbertubing to deaden noises. It is apparent that, within the scope of theinvention modifications and different arrangements may be made otherthan is herein disclosed, and the present disclosure is illustrativemerely, the invention comprehending all variations thereof. 1

4. A lever formed of sheet material-having a portion thereofsubstantially U-shaped in cross section, the walls of said U-shapedportion having axially aligned openings of difierent diameters; abushing extending into said openings; and means forming a part of saidbushing engaging with one wall of said lever to hold said bushing andlever in fixed relation.

5. A lever formed of sheet material and having a substantially U-shapedportion at one. end thereof, the walls of said U-shaped .portion havingaxially aligned openings of diflerent diameters; a bushing extendinginto said openings, said bushing having shoulders enga in with therespective walls of said U-shaped portion for of said U-shaped portionhaving axially aligned openings of different diameters; a bushingextending into said openings, said bushing having shoulders engagingwith the respective walls of said U-shaped portion for holding saidwalls in spaced relation; and a portion of said bushing being swedged tohold said bushing and lever in fixed relation.

'7. A lever formed of sheet material and having a substantially U-shapedportion, the walls of said U-shaped portion having axially alignedopenings of different diameters; a bushing extending into said openings,said bushing having shoulders engaging with the respective walls of saidU-shaped portion for holding said walls in spaced relation; a shaft insaid bushing having a shoulder thereon; and means including a spring forholding said shaft in one position.

8. A lever formed of sheet material and having a substantially U-shapedportion, the walls of said U-shaped portion having axially alignedopenings of different diameters; a bushing extending into said openings,said bushing having shoulders engaging with the respective walls of saidU-shaped portioiffgfor holding said walls in spaced relation, saidbushing having an opening; a shaft in said opening having a shoulderadapted for engagement with. a portion of said bushing; a washer carriedby said shaft; and

means including a spring interposed between said washer and said bushingfor holding the parts in fixed relation.
